Declare MIPS stat nanoseconds fields similarly to other architectures

Declare MIPS stat nanoseconds fields similarly to other architectures

[Joseph S. Myers]

I noticed that the MIPS bits/stat.h was different from other architectures 
in how it handled nanoseconds fields: in the case where struct timespec 
fields were not being declared, the nanoseconds were __reserved* instead 
of having st_atimensec etc. names.  I've applied this patch to make MIPS 
consistent in the API provided with other architectures.  (There are no 
layout issues since "unsigned long", the type used elsewhere for 
nanoseconds, is consistent with the type in struct timespec, and on n64 
where the fields were "int" (32-bit) and now are "unsigned long" (64-bit) 
that "int" was always followed by 32 bits of padding since both __time_t 
and __blksize_t were 64-bit in that case.)
